Disgraced former speaker Bronwyn Bishop has launched a passionate defence of her taxpayer-funded travel, declaring she "did nothing wrong" after a report into her expenses said she did not fully cooperate with the investigation.

Key points:

Bronwyn Bishop was silent about hundreds of travel claims

She said she did not want to "open her life to the world"

Ms Bishop said Telmo Languiller, Don Nardella deserved more coverage than she did

The Herald Sun has obtained the official report into her travel expenses showing she repaid nearly $14,000 to the Commonwealth, including for trips to three colleagues' weddings and travel to businessman Kerry Packer's funeral.

The Finance Department report also highlights Ms Bishop's reluctance to help investigators, saying the information she provided was "in large part, lacking in any detail".

It said she stayed silent about hundreds of travel claims because she did not want to "open her life to the world".

"As the department is reliant on information provided by Ms Bishop to fulfil its role in the exercise, no further assessment is possible in relation to the incomplete seven years," the report said.

Ms Bishop lashed out at the media for its focus on her spending, which she defended as being "quite within the rules".
